COMBINED BUMPER AND JACK.

' Applicationfll'ed flctober 3', 1924. Serial No. 741,464.

To all whom concern:

Be it known that I, GUSTAF SJOLANDER,

a citizen of the United States, residing at Midland, in the countyof Midland and State of Michigan, have invented new and useful Improvements in Combined Bumpers the provision-of a combined bumper and jack, which will act as a protector for the vehicle when used as a bum er and which will also provide means for ifting said vehicle when used as a jack.

More specifically, the present invention aims to provide a nove construction 0 bumper and jack which may be readily adjusted for either use and when used as a bumper will provide a strong, durable and attractive device which may be easily and quilclszly converted into a pair of lifting With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a front elevation of a portion of an automobile with the invention arranged to provide a bumper.

Figure 2 is a top lan view of the front ortionloi an automo ile with the invention 1n use as a bumper, parts being broken away.

Figure 3 is a fragmentary, top plan view of the invention per. se, the bumpersections being shown disconnected.

Fi ure 4 is a fragmentary front elevation showing the device used as a jack.

Figure 5 is a. vertical sectional view of the same.

Figure 6 is an enlarged fragmentary v1ew partly in section showing one end of. one of the bumper sections,

Figure 7 isa detail elevation of one of the sleeves.

Figure 8 is a similar view. lifting screws.

of oneof the Figure 9 1s asectional view'of a nut. I

Figure 10 is a sectional 'view showing a modified form of the invention.

Fi ure 11 is an enlarged sectional view showing the valve illustrated in Fi re'lO.

Referring to the drawings in detai wherein like characters of reference denote corresponding parts, the device is shown as comprisin a pair of tubular members 15, each of w ich is adapted for use as a jack, as shown in Figures 4 and 5 of the drawings and also adapted to be connected to form a bumper bar as shown in Figures 1 and 2 of the drawin s.

For the purpose 0 providing a 'ack, each of the tubular members 15 has -t readedly or otherwise secured thereto a foot 16, while extending longitudinally of each of these members is a screw 17. I

The screws 17 have secured upon one end a head 18 which is provided with openings f 19 for the reception of a removable bar 20,

the latter being carried in the tool box or some other convenient ortion of the automobile. Th lower en of the screw 17 is reduced to provide a shoulder 21 against whichbears a washer 22 and between this a washer and the bottom 23 of the foot 16 is an anti-friction bearing 24. The screw is held in place by any suitable means, such as a pin 25 and washer 26 which bears a ainst the under face of the bottom 23 o the foot 16. A thrust .bearin is thus provided in which the lower en of the screw is swiveled.

' Located within the tubular members 15 are nuts 27 which are provided withextensions 28, the said extensions projecting through elongated slots 29 provided in the members 15. Relative longitudinal move-. ment between the nuts and tubular members is thus possible. i

Pivotallv secured to the extensions 28 of the nuts 27 as shown at 30 are rods 31-, the latter havin a sliding engagement within sleeves 32 w ich are carried by plates 33, the latter being clamped to the frame of the automobile by means of U-bolts 34.

Springs35 surround the rods 31 .and bear front and of course may be duplicated upon pose the rods 31 are capable of rotation in the sleeves 32 and have a pivotal connection with the nuts 27. Thus, the tubular members 15 may be horizontally aligned and when in this position may be connected by sleeves 38. The sleeves 38 receive the upper or inner ends of the tubular members and the latter are removably held in position by means or set screws 39. As shown in Figure 3 of the drawings, the set screws are released and the sleeve 38 is moved longitudinally inward so as to release one of the tubular members 15. The sleeve 38 may then be entirely. removed from the other tubular member, whereupon the said members may be swung to a vertical position for use as jacks.

In Figures 10 and 11 the tubular member 15 has its inner or upper end closed by a plug 4:O,'while ablock 41 is substituted for the nut 27. This block is connected to one end of a rod 42 whose opposite end is secured to a piston 43. A valve 44 is secured to the tubular member 15 beyond the piston 32 and is provided with a nipple 45 for conncction with a suitable source of air under pressure, so that when the valve is opened, the iston will be forced upward. A pneuma-t1cally operated jack is thus provided. The valve 44 is of the two-way type and is provided with a discharge port 46 so that pressure from the tubular member 15 may be relieved and the block 41 lowered.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

I-Iaving described the invention what is claimed 1s:- v

1. A combined bumper and jack comprising a sectional bar, each of said sections being of tubular construction, means "for at taching the sections to a vehicle, means whereby the sections may be moved relatively to the attaching means for use as jacks and means for detachably connecting the sections in horizontal alignment to provide a. bumper bar.

2. A combined bumperand jack for vehimenace cles comprising a sectionalv bar, means carried by each section for attachment to a vehicle, means whereby the sections may be moved relatively to the'attaching means for useas jacks and a telescopic connection for the sections to define a bumper bar.

3. A combined bumper and jack for vehicles comprising a sectional bar, each of said sections being of tubular construction, a member located within and slidingly engaging each section, means connectingthe members with the vehicle, means located within the sections and operatively connected to the members, whereby the sections may be moved longitudinally for use as jacks and means for detachably connecting the sections to provide a bumperbar.

4. A combined bumper and jack for vehicles comprising a sectional bar, each of said sections being of tubular construction, a member located within and slidingly engaging each section, a rod pivotally connected dinally of each section and engaging the nut,

means whereby the sections may be rotated to move said sections longitudinally for. use as acks and means for detachabl connectingthe sections to provide a bum er bar.

6-. A combined bumper and jac for vehicIescOmpr smg a sectional bar, each of said sections emg of tubular construction, a nut located within and slidingly engaging each section, means connecting the nut with the vehicle, a threaded rod extending longitudi nally of each section and engaging the nut, a thrust bearing connection between the inner end of the rod and section, whereby the sections may be moved longitudinally for use as jacks and means "for detachably connecting the sections to provide a bumper bar.

In testimony whereof I afix my signature.

GUSTAF SJOLANDER.
